application filed July 6, 1916, Serial No. 197,818.

To all whom it may concern Be it known that 1, JOHN MILLER, a citizen of the United States, residing at Dow Cit in the county of Crawford and State explode the gas or volatile fuel, and admit the expanding gas to the means operating to drive the power shaft.

' I particularly aim to provide a valve means operable by the ressure or" the volatile fuel to o 'en-and a mit the volatile fuel to a combustion chamber and a valve means operable to permit escape of the fuel from t e combustion chamber to the power shaft driviingmeans as a result of combustion and expans on of the fuel while in the combustion chamber.

Further I a'im to provide a device of the construction hereinafter set forth possessing I the additional objects and advantages to be pointed out in relation thereto as the description progresses and which is to be taken in connection with accompanying drawings.

In said drawings: 4 Figure 1 is a longitudinal sectional view through my improved motor;

Fig. 2 is a vertical transverse sectional View, t n substantially on the line 2-2 of Fig. lrorough the entire motor;

mg". 3 is a cross sectional view on the line -33 of i;

Fig. 4% is a cross sectional view on the line H of Fig. l; and r g. 5 is a cross sectional view on the line 2 tliroug h a complete rotor Referring specifically to the drawings, a.

suitable casing or housing to support and contair the various parts is provided and 1s preferably formed in a plurality of sections advisably from cast metal but manufactured in'any approved manner. Said casing or housing may comprise a fuel superheating section A, a closure or chimney section B therefor, a combustion section C, a closure section for the combustion section D, a rotor containing section E and sidewalls or closure plates F for the rotor section.

explosive nature may be used, et the pres ent engine or motor is designed to be operated particularly by means of crude oil which flows from any suitable source into and through the pipe or coil 6 which is supported in a side wall of section A and on :1 lug? of the said section. The coil 6 communicates with a passageway 8 formed in termediate a wall 9 of section B and a side Wall of the section A. Crude oil while within the coil 6 is superheated so that it will emerge from the coil into the passageway 8 as a gas or in a volatile state. Any suitable means may be emploved to superheat the oil for instance the burner shown which has a hollow casing 10 provided with perforations 11in its top for the escape of gas which is preferably supplied to the interior thereof through the means of a supply conduit 12 and branches 13' thereof. Two of the branches 13 are supported by means or brackets 14 from the casing 10 While the other branch rests on an arc ate support 15 forming part of the casing Ml? Gas supplied through pipes 12 and 13 passes into the burner casing and emerges therefrom through the openings or orifices 11 and is then ignited by a spark produced by the closing of an electric circuit in any suitable manner through a spark plug 16 mounted in a side wall of 6218111 A. The flame produced acts on the coil 6 and superheats the oil therein while the surplus heat and smoke is deflected upwardly by means of stack or chimney walls 17 inte ral with and depending from section B and leading to a short vstack 18 covered by a perforated hood 19.

Sections A and B are detachably connected together as by means of bolts or screws as The passageway 8 communicateswith a assageway 8 provided in the section C and is normally closed by means of a valve 21' engageable with a valve seat at 22 of the section C. The valve 21in its movementis guided by a Wall 23 which terminates short of the section D so that the fuel passing the valve 21 will enter a combustion chamber 24 provided in the-section C and closed by the section D. The outlet of the combustion chamber which is at a valve seat 25 is normally closed by means of a valve 26 which slides in a valve chamber 27 and which communicates with assageways 28 and 28 provided respective l' in the sections C and E. A spark plug 29 is mounted in the wall of and at its upper extremity abuts the arch 33 so to normally maintain the valve 21 seated and urge it toward its seat. The spring 35 on the other hand is connected at its upper extremity to the stem 32 and at its lower extremity bears on the plate 30 and thustends to raise the valve 26 and restore it toits seat after depression.

Set screws or bolts 36 may be utilized to secure the sections A and B to section D while set screws or bolts 37 may serve to detachably connect the sections C and E"-to gether and set screws 'or bolts 38, 39 and 4:0,

may be used to effectively detachably connect the sections D, Cand A to the section E. The sid walls F are detachably secured to the section E by means of bolts 41.

Within the section E intermediate the side walls F a suitable form of rotor is provided. This rotor may comprise a hub 42 preferably integral With disk like sides 43 provided with radially disposed dove tail grooves at in which slide blades 45 by means of ribs 46 of dove tailed cross section, disposed in the grooves. Each blade 4.5 has a spoke 4C7 integral with it and mounted in a socket 48 of the hub. The sockets communicate with an annular recess 49 in which a suitable spring, for instance a ringbO is disposed, and which bears against the inner ends of the spokes 47 and urges the blade 45 outwardly and the ends thereof intov effective wiping relation with theannular wall of the rotor chamber. The hub 42 is keyed to a shaft 51 which is journalcd in bushings 52 carried by the plates F and on which shaft a fly Wheel 53 is preferably mounted. Power from the shaft 51 may be transmitted in any suitable manner and by Way of examplclhave shown a pulley 54 keyed to the shaft and over which a belt may be trained which is also trained over the pulley of the mechanism driven from the shaft. 1

in operation, the crude oil passing through the coil (Sis superheated or vaporized by the action of the burner mechanism below it. This mechanism as stated supplies gaseous fuel to the interior of the casing 10 and whichfen'ierges through the orifices 11 thereof and .isf-ignitcdby a spark produced upon the-closing of an electric circuit through the spark plug 16. If thefuel used willrcadily vaporize, as-does gasolene, the superhcating mechanism need not be operated. Gaseous paneling gases are liberated in the rotor sion of the gases and their expansion, valve 26 is depressed so'that the products of explosion may bypass it -into the conduits 28 and 28 and thence into the rotor chamber so as to act by impingement against the blades 45 and thus turn the rotor and the shaft 51 from which power may be transmitted. The gas after spending its force in the rotor chamber escapes therefrom through an exhaust pipe 55'leading to the atmosphere and disposed in the section E. It willv be realized that the supply of crude oil is continuous and that therefore successive charges are supplied to the combustion chamber 24 and ignited so that successive volumes of ex chamber to impinge against the rotor and thus keep it in continuous rotation.

Since merely the preferred embodiment of the invention has been illustrated and described, it is to be understood that changes in the details of construction may be resorted to within the spirit and scope of the invention.
